Processing
Adopting premium D374N imported carbon material with fine graphite and copper powder ratio, the carbon brush features uniform texture and stable electrical conductivity. After precise cutting, polishing and high-pressure forming processes, it will also with low friction coefficient and excellent heat dissipation. It effectively suppresses electric abrasion and commutator wear during long-term high-frequency operation. Boasting strong adaptability to harsh industrial environments, it maintains consistent working performance, lowers equipment failure rates, and greatly optimizes daily motor operation and maintenance efficiency.
